A plastic rod that has been charged to 14nC touches a metal sphere. Afterward, the rod's charge is 6.0nC. Part B How many charged particles were transferred? Express your answer using two significant figures. i Incorrect; Try Again; 5 attempts remaining You have a lightweight spring whose unstretched length is 4.0cm. First, you attach one end of the spring to the ceiling and hang a 3.0g mass from it. What is the magnitude of the charge (in nC ) on each bead? This stretches the spring to a length of 5.0cm. Express your answer using two significant figures. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.7cm. 3 Incorrect; Try Again; 3 attempts remaining
